Hey,
did you also check this guideline?
Interval Max * (Slave Latency + 1) * 3 < connSupervisionTimeout
Also, slave latency is not a value in milliseconds, but is a number of connection events that your peripheral may skip while sleeping.

I have been trying to use the L2CAP Connection Parameter to change the Bluetooth 4.0 (BLE stack) Connection Interval in iOS 6.1.x. The 30ms default causes my device to consume too much power. I've followed
the Bluetooth Accessory Design Guidelines for Apple Products and used the following setting:
Preferred Timeout: 6seconds
Preferred Minimum Interval: 800ms
Preferred Maximum Interval: 1000ms
Preferred Slave Latency: 0ms.
but everytime after updating, iphone5 will lose connection with my device.
and next time i try again, iphone5 will lose connection again.
but i think i fullly comply with Apple rule as above.
So why i can't update interval, please help me to solve this problem, thanks.
